Agricultural vehicles cool down in summer
First, the use of lubricants. In order to ensure the temperature, lubrication, and normal operation of the parts, the 11th diesel engine lubricating oil should be selected in summer, and the gearbox and rear axle should be used 30# gear oil. When replacing the gear oil, the crude oil should be drained and cleaned before putting in new gear oil.
Second, keep the tank clean. If there are many rainy days during the summer, if the water tank is not cleaned in time after the rain, dust and oil will quickly pollute the water tank, making it difficult to dissipate heat from the tank and water jacket. Accumulation of more scale inside the radiator can easily lead to damage to the cylinder. Therefore, attention should always be paid to the cleaning of the tank and the outside of the radiator.
Third, check the cooling system in time. In daily work, the cooling water should be sufficient and the fan belt tightness should be appropriate. The thermostat and water temperature meter should be checked and maintained in time. Found that the tank "open pot" should stop in time, idling temperature, can not suddenly join the cold water.
Fourth, beware of interruption of fuel supply. High temperatures can cause air resistance in the oil supply system, resulting in insufficient oil supply or interruption. For this purpose, the hand oil pump oil is used before start-up, the air in the oil circuit is eliminated, and the ventilation in the engine hood is ensured, and heat insulation measures are taken for the heated part of the oil circuit. In addition, the oil supply system should use the standard No. 0 diesel oil, and it should be precipitated regularly to release the lower water.
Fifth, timely adjustment of battery fluid. The battery electrolytic density is adjusted from 1.28 to 1.29 for winter use to 1.25 to 1.26 for summer use. The electrolyte level is checked every 8 to 10 days. The liquid level should be 10 to 15 millimeters above the plate, and additional distilled water should be added when it is insufficient. Appropriately reduce the generator's charge flow to prevent the battery from overcharging; prevent the vent hole on the battery cover from being blocked by the pumped electrolyte, causing the battery to explode.
Six, hot car slow cooling. Hot weather in summer, hot road surface, combined with large body loads, such as poor maintenance, it is prone to cylinder cracking, tire inflation and so on. Therefore, in addition to not having enough excess fetal gas in summer, you should also perform slow cooling. The hot car can be parked in the shade and cool, or the cooling equipment can be added in the garage. In addition, the paint remover shall be rusted and painted or greased with rust. The tank should be filled with water to prevent rust inside the radiator.
Viruses and bacteria are everywhere. Preventing them in advance is the best way to reduce the risk of infection. Wearing a mask and washing hands frequently are crucial. The new type of coronavirus has the characteristics of contact transmission, and the fact that the virus exists on the doorknob of patients with pneumonia has also shown the necessity of paying attention to hand hygiene and wearing disposable protective gloves.
Whether it is going out to purchase daily necessities or buying through online platforms, it is inevitable to come into contact with "foreign" items, such as supermarket shopping carts, packaging bags, express packaging boxes, etc., and more things need to be touched after resuming work, such as It is inevitable to take public transportation, elevators, etc., these places may have been touched by patients or suspected patients. Wearing disposable protective gloves is an effective means to reduce the risk of infection when there is no condition to wash your hands at any time.
